Special Features

  • The raindrop sensor module adjusts the sensitivity through a potentiometer, and the working voltage is 3.3V-5V, ensuring adaptability to various power supplies; LM393 uses a wide voltage comparator, with clean signals, good waveform, strong driving capabilities, and greater than 15mA.
  • Easy to use: Connect a 5V power supply, the power light is on, there is no water drop on the sensor board, the DO output is high, the switch light is off, drop a drop of water, the DO output is low, the switch indicator light is on, wipe off the water drop, and restore again, and output a high level state.
  • The sensor uses high-quality FR-04 double-head material, with nickel-plated surface treatment, which has superior performance such as anti-oxidation, conductivity, and life, and is equipped with a potentiometer sensitivity adjustment; it is equipped with a fixing bolt hole for easy installation.
  • Dual output format: Provides digital switch output (0 and 1) for easy integration into digital circuits, as well as analog AO voltage output for more accurate measurement and application.
  • The raindrop board and the control board are separate, which is convenient for lead-in, TTL level output, and the effective signal of TTL output is low level. The driving capacity is about 100MA, which can directly drive relays, buzzers, small fans, etc.

7. Small board PCB size: 32mm x 14mm
8. Large plate PCB size: 50mm x 40mm

Function introduction:

Connect the 5V power supply, the power indicator light is bright, and when there is no water droplet on the inductive board, the DO output is high level, the switch indicator light is extinguished, a drop of water, the DO output is low level, the switch indicator light is on,Brush off the water droplets above and return to the high level of output.

AO simulation output can connect the amount of rain on top of the AD port of the single -chip microcomputer.

Do TTL digital output can also connect the single -chip microcomputer to detect whether there is rain.

Wiring method:
1.VCC: Plot power positive (3-5V)
2.GND: connect the power supply pole
3.Do:ttl switch signal output
4.ao: Sims signal output

Product use:
Robot kit, raindrops, rain sensors, can be used for monitoring of various weather conditions, and converted into number signal and AO output.

Package contains:
6PCS Water Sensor Rainwater Module
